Irrigation and Melioration


Article brings up the advantage of confusor part application in outflow part of vortex spillway, which may be more rational from the point of view of providing non-cavitation operation of flow swirler. Analytical design method and program developed is given of pressure and specific energy for aerated part of swirled flow in vortex spillway confusor part, which match with experimental results, it allows for fast and quite accurate realization of distribution analysis for pressure and specific energy in swirled flow along the length of the confusor for various rates of taper.
